THOMAS MIIELS, OF MIDDLETON JUNCTION, ENGLAND.

GUARD FOR THE SCROLLS OF SPINNING-MULES.

To all whom it may concern Be it known that I, THOMAS MILLS, a subject'of the Kingof Great Britain and Ireland, and a resident of Middleton J unction, in the county of Lancaster, England,

have invented certain new and useful Tmprovements in Guards for the Scrolls of Spinning-h Iules, of which the following is a specification.

' This invention relates to guards for the scrolls on the back shafts of spinning mules and has for its object to provide an improved guard especially applicable for end scrolls and which, while affording an eflicient protection, will permit of access to the scroll for the purpose of piecing the scroll band or rope when broken or other purposes without removing it or any part of it and which also can be readily fitted A guard in accordance with this invention comprises a main or inclosing part closed at the top, bottom and rear and open at the front and adapted to inclose the scroll, and a front part adapted to close the open front of the main or inclosing part when the guard is fitted in position, said main or inclosing part being provided with an opening fitted with a door or cover for giving access to the interior of the guard.

The accompanying drawing illustrates one form of guard according to the invention, Figure 1 being a perspective view of the complete guard, Fig. 2 a perspective view of the main part and Fig. 3 a like view of the front part. Fig. at is a transverse section and Fig. 5 a longitudinal section and Fig. 6 a plan of the guard.

Referring to the drawing, a is the main part of the guard and 7) the front part thereof. The main part a is of more or less U shape in cross section with the opening at the front. The. ends of the part a are slotted at c to clear the back shaft and enable the part to be placed thereon or thereover to inclose the scrolls.

The front part .7) has its edges flanged over and is fitted in the open front of the main part a, when the latter has been arranged in position on the back shaft, to complete the inclosure of the scrolls. The front part b is secured to the main part a by set screws (1. Holes or slots are provided in the front part b for the passages of the scroll bands or ropes to and from the scrolls inclosed bv the guard. These holes are pref e13 with Specification of Letters Patent.
